Austria

Vienna's cathedral has survived many wars and is now a symbol of the city's freedom. The Gothic cathedral was first built in 1147 and its most recognizable characteristic, the diamond-patterned tile roof, was added in 1952.

Nestled high in the Alpine mountains of Austria, the Shrine of Our Lady of Mariazell is the most popular Marian shrine in Central Europe. The shrine centers on a miraculous statue of the Virgin Mary discovered by a monk in 1157.

Built in the 13th century over an earlier church, this small edifice next to the cathedral is interesting for its venerable age and mixture of styles. The semicircular choir features elaborate vaults and nine chapels.
